[Delphi]一个解析FTP地址的小函数

procedure TForm1.FTPAnalysis(S:string;var UserName,Password,IP,FileName:String;var DirList:TStringList);

var

i,j:integer;

strAuthorization,strAddr,strDirFile:string;//授权信息

begin

UserName:= 'anonymous';

Password:= 'test@test.com';

IP := '';

strAddr := Copy(S,7,length(S)-6);//取得ftp://之后的部分

//S 格式必须是类似ftp://rec:ooo@192.168.76.11/20050418/abcdef.vox，或ftp://192.168.76.11/......

i := Pos('@',S);

if(i>0) then

begin

strAuthorization := Copy(S,7,i-7); //只取帐号密码字段

j:=Pos(':',strAuthorization);

if(j<1)then

exit;

UserName := Copy(strAuthorization,1,j-1);

PassWord := Copy(strAuthorization,j+1,length(strAuthorization)-j);

end;

i := Pos('@',strAddr);

j:=Pos('/',strAddr);

if(j>0) then

IP := Copy(strAddr,i+1,j-i-1);//获得IP地址

strDirFile := Copy(strAddr,j+1,length(strAddr)-j);

DirList.Delimiter := '/';

DirList.DelimitedText := strDirFile;//获得目录列表

FileName := DirList[DirList.count-1];//最后部分为文件名

DirList.Delete(DirList.Count-1);

end;
